Check engine code??

[acontour]

Hi guys,

What is up with these Contours..I fix a check engine light than after a while I get another one.I fixed a lean code , Temp switch harness code , o2 sensor code , a DPFE code , and probably more. :crazy:

Now i'm stuck with1401 DPFE sensor circuit high voltage

The only thing i found online is to check the Egr valve by applying vacum pressure. If the car stalls than the EGR is good. I can check the DPFE sensor ,and change it just in case ,even though it's like about 8 months old.

If anyone ran into this and knows how to fix it , I would greatly appriciate it.

Thanks

?

So nobody knows??

I unplugged the egr valve hose and sucked on it to confirm that it's working, and it does stall the car..
Damn P1401 code

P1401:
DPF EGR circuit open
VREF short to PWR
Damaged DPF EGR sensor
DPFEGR circuit short to PWR
SIG RTN circuit open
Damaged PCM

It's most likely that wires are shorted somewhere in the circuit; IIRC, there was a wire disintegration recall for '95-'97 'tours.
